To all whom it may 00mm:

Be it known that I, CARL IssnNMANN, subject of Switzerland, residing at Erlangen, Germany, have invented certain new and useful Improvements in a Paper-Pulp- Strip-Producing Machine, (Germany, filed November 10, 1917 Germany, filed J anuary 30,1918; Austria, filed March 22, 1918;

Switzerland, April 17, 1918; Sweden, filed April 18, 1918; Hungary, November 5, 1918; Denmark, November 1, 1918; Norway, November 18, 1918; Netherlands, November 9, 1918; Belgium, filed December 2, 1918; Finland, filed November 27, 1918; Luxemburg, filed October 30, 1918; Rumania, filed November 13, 1918, and Czecho-Slovakia, filed April 9, 1920,) of which the following is a specification.

In carrying out the method of producing fibrous strips according to the wet spinning system the reeling of the strips has met with considerable difiiculties and particularly the leading or guiding of the strips to the spools was difficult, nomatter whether the reeling of thest'rips is carried out in the ordinary way or whether the strips run on to the reciprocating spools to obtain spirally crossing layers. The passing or leading over of the unrounded rovings freely to the spools requires a considerable amount of exercise or practice and if not very great care is taken in carryin out this work, a large amount of waste Wlll be the consequence due to breakage of the very narrow roving strips or to felting of one layer with another and therefore thepromachine will be reduced to a corresponding extent. 1

According to the present invention the passing or leading over of the strips from the distributing cylinder freely to a number of spooling devices arranged at a more or less great distance from the cylinder is perfectly avoided. The strips are reeled up directly from a moving surface of the paper making machine, for instance from the strip distributing cylinder or from the felt apron or from an intermediate carrier roll, which contacts with the said moving surface of the machine and also with the spool. In each case the rotation of the spool or reel will be obtained by the direct contact with the stri carrier of the paper making machine. hen more than one delivery places are used, a similar distribution can be car ried out as has been the case by the aid Specification of Iietters Patent.

of distributing rollers.

In this manner the advantage is gained that the distributing cylinder, which is comparatively expensive, can be left away altogether. Thus the machine is simplified and the operation'is facilitated.

In the drawing different reeling devices are shown constructed according to the present invention 1 Figural is a diagrammatical section of a device having a number of reeling spools and w Figure 2 is aplanof this device. I Figure 3 is a similar view in which specialintermediate carrier rollers are usech Figure 4 isa plan of device having onlya single spoo. I Figure 5 is a diagrammatical section of a device, in which the strips are taken iniinediately fromthe felt apron and I Figure 6 is a. plan ofthe last named de- Figure 7 is a section of the device, in which a carrier roll is used in connection with the'device shown in Figure 5.

Figure 8 is the end view of a single spool. In the mode of construction shown in Figures 1 and 2 the device is shown in connection with. a distributing cylinder a rotated in any known manner. The strips are reeled on spools b, 5 which are in direct contact with the cylinder a. If there are three spools, as shown in Figure 2, each spool has about distributing cylinder In the construction shown in Figure 3 intermediate carrier rolls 0 are arranged between the speols Z) and the cylinder at, by which carrier rolls a short distance between the spool and the cylinder is overbridged without allowing a free leading over or passing over from the cylinder to the spools In the constructionshown in Figure 4. a single reeling roll 6 is shown, which also either contacts directly with the strip dis tributing cylinder a or an intermediate carrier roll 0. V

In all cases stated above the rotation of the spools is effected by the contact with the cylinder or the rolls. The shafts d for the spools b may carry special tubes 6, Figure 8, so as to enable a convenient separation of the disks of strips formed by the reeling up of these strips.

. f th breadth of the intermediate carrier rollers as long as they are strong enough guiding rollere roller for a spool torconta'ct with the apron for the pressure exerted by the reelingv operation. As a rule it might be advantageous to give the counter roller a somewhat greater diameter. Evidently also the lower can be used as a counter at this place. The invention is not limited to the number of spools to be laid on the cylinder a or the apron f. If the apron is held "sufiiciently taut, the counter rollers may be dispensed with in certain cases. In all cases only the pressure necessary to r0- tat'e the spools by contact with the surface that transfers the narrow roving strips to themisused, as otherwise breakage of the delicate narrow web, and felting or one turn to the other will occur, as the roving strip isiwet. If felting should occur, the rovings cannot be unwound again for subsequent rolling into threads. V

I claim: r

1. In a machine for making narrow thin roller forthe spools b paper rovings, the combination with a moving surface carrying a roving strip; of a spool on which said rovings are wound in contact with said surface. I I

'2. In a machine for making narrow, thin paper rovings, the combination with a moving surface carrying a plurality of narrow roving strips side by side; of a spool on which said strips are wound in non-felting contact with said surface. ,o

3. In a machine for making narrow, thin paper rovings, the combination with a moving surface carrying roving strips; of a counter roll for said surface and a spool. in non-"felting driving contact withsaid'rollr at. In a machine for making narrow, thin paper rovings, the combination with a movingsurface-carrying narrow roving strips spaced apart; of a distributing cylinder, a spool for receiving the rovings and an'interinediate' carrier roll contacting with both cylinder and spool. 1

5. In a machine for making thin, narrow paper rovings, the combination with a movingsur'face on whichv thin,'narrow, wet rovings strips are spaced apart, a spool on which said rovings are wound, and an inter mediate carrier roll contacting with said surface and also in non-felting contact with said spool.
